Vehicle Valuations for Legal, Insurance, Divorce & Taxation

Specialist Car Valuations: non-AI UK Independent Expert Witness Car Valuer

About Specialist Car Valuations

Established in 2004, Specialist Car Valuations is led by John Glynn. I am an independent vehicle valuation expert providing court, tax, insurance and specialist valuation services across the UK and internationally.

With a 30-year career as a professional car valuer, including ten years as a Glass’s Guide Editor across classic and collector cars and consumer market values, I provide defensible vehicle valuations for high-value and disputed matters, including divorce, probate, proceeds of crime and civil litigation. My work is used where the figure must withstand challenge.

I have valued hundreds of thousands of vehicles across all sectors of the market. This depth of experience underpins every report. Every valuation is researched, assessed and signed by me. I do not delegate valuation opinions to junior staff or AI systems. My conclusions reflect the individual vehicle, the evidence available and the market in which it would be sold.

Services include:

Expert Witness Reports for Family, Civil, and Criminal Court
Divorce Valuations: Single Joint Expert or Sole Party
Legal Aid work for Proceeds of Crime/POCA Reports
Shadow Expert Work: Critical Analysis of reports by other Experts
HMRC & Taxation Valuations for the UK and Worldwide
Insurance Write-off and Disputed Market Valuations for Ombudsman and Legal Proceedings

I provide independent expert vehicle valuation reports for classic and modified cars, modern supercars, race cars, motorhomes, military, agricultural, commercial and specialist vehicles of all ages.

My work is instructed where a valuation is unclear, contested, does not reflect the real market position or when a past value is called for. Reports are prepared by me in person and valuations are never AI-generated.

As a member of the UK Register of Expert Witnesses, my reports comply with Civil Procedure Rules Part 35, Family Procedure Rules Part 25 and Criminal Procedure Rules Part 19.

The power of a detailed, transparent and defensible report can be seen in the number of cases I work on that settle in pre-trial mediation. Instructing solicitors have expressed how my clearly expressed, evidence-based valuations bring both sides to the table with a different mindset.

Professional Experience & Court Proceedings

I have extensive experience preparing independent expert valuation evidence for civil, family and criminal proceedings. My work includes instructions from leading UK law firms, court-directed Single Joint Expert appointments and valuations for substantial financial disputes.

Williams v Williams [2024] EWFC 275 – High Court, Family Division

In published financial remedy proceedings for a billion-pound divorce before Mr Justice Moor, I was instructed by Vardags and named in the judgment as having valued a collection of motor vehicles, together with cherished registration numbers.

Horlick v Jhally – Central London County Court

Instructed in proceedings involving a classic Porsche 911, I prepared independent vehicle valuation evidence in litigation conducted by Mishcon de Reya. The dispute proceeded to judgement of £114k in favour of the Claimant and received national press coverage.

Aldermore Bank v Garrod (2025) – Commercial Litigation

I provided independent expert vehicle valuation evidence in an extremely complex case for Aldermore Bank plc, instructed through Pinsent Masons. The bank was represented by barrister James McWilliams, whose practice specialises in complex commercial litigation and financial disputes. I was required to give evidence and was cross-examined.

Court-Directed Single Joint Expert Appointments

I am regularly appointed as a Single Joint Expert in financial remedy proceedings in civil and family matters, including appointments formally recorded in court orders. My reports are prepared in accordance with FPR Part 25 or CPR Part 35. I also work outside the UK. My experience includes joint expert statements and heavily contested valuation matters.

Confidentiality is maintained in all instructions, and details of private family, civil and criminal proceedings are not disclosed.

My expertise includes cherished registration valuations, classic motorcycle valuations and more. Contact me to talk in confidence.

John Glynn - Independent Car Expert Valuer UK

Thirty Years of Professional Valuation Experience. Evidence Tested in Legal Proceedings.

My motor trade history dates back to 1986, and includes more than three decades of professional valuation experience, hundreds of articles in the UK motoring press, a book on classic Porsches and media appearances including BBC Radio 4.

I spent ten years as Valuations Editor with UK motor trade price bible Glass’s Guide, where I managed and developed several vehicle Guides and a number of groundbreaking digital products, including the first ‘We Buy Any Car’ online car valuation algorithms, and helped create automatic valuation systems that remain in use today. I now address vehicle valuation questions for all courts without the use of AI or machine technology. I write every valuation report in person.

I am the only independent vehicle valuer endorsed in name by leading UK insurers including Adrian Flux, Footman James, Classicline, Carole Nash, Locktons and the NFU. I have served many banks and insurers as their Expert Witness in court and as an asset valuer for collector car finance agreements.

I am a vetted member of the UK Register of Expert Witnesses. My valuations are accepted by HMRC and relied upon in civil, family and criminal court cases and in high-value legal proceedings.

My pre-Expert Witness experience spans the full spectrum of the motor trade. I have bought, sold, written about and valued everything from early classic cars to supercars, veteran motorcycles, racing cars, vintage tractors, motorhomes, cherished plates and more.

I have extensive experience in historic motorsport, as a previous co-owner of Amsterdam-based Twinspark Racing, over 18 years with Tuthill Porsche including marketing and car sourcing and long associations with UK classic car restorers and repairers.

Well known for my Classic Motorcycle Valuations and Classic Car Valuations, my honesty and integrity means that most customers are repeat clients or referrals. I consult on valuations for all sorts of vehicles. I deliver detailed, independent expert valuation reports for solicitors and other professionals, regardless of case complexity, based on decades of professional valuation experience.

Contact me to discuss my services. I work with absolute discretion and your privacy is assured.

I would highly recommend John's work as an expert specialist car valuer. John not only knows his stuff but is also a brilliant person to work with. I cannot recommend John highly enough.

Are you an experienced vehicle valuation expert witness for High Court litigation?

I have over 30 years’ professional vehicle valuation experience and am a member of the UK Register of Expert Witnesses. My valuation evidence is referenced in published High Court judgments. My litigation experience includes high contentious instructions involving Mishcon de Reya, Vardags and Pinsent Masons and hundreds of more straightforward valuation instructions.

Can you value a substantial collection of classic or high-value cars for divorce proceedings?

I prepare independent valuations of classic, collector, prestige and specialist vehicles for financial remedy proceedings. I am regularly appointed as a Single Joint Expert, including through formal court orders. Reports are prepared in accordance with FPR Part 25.

As an independent expert, can you challenge an insurance company’s vehicle valuation?

I prepare independent valuation reports for disputed insurance total losses, including cases submitted to the Financial Ombudsman Service. Reports consider individual vehicle condition, specification, history and relevant market evidence rather than relying solely on automated vehicle valuation systems.

Can you provide independent vehicle valuations for HMRC, taxation and company accounts?

I create bespoke valuations for HMRC, inheritance tax, retrospective taxation assessments, company asset transfers and business transactions. Instructions include classic vehicles, specialist cars, motorcycles and commercial vehicles, with valuation opinions supported by appropriate market research.

Do your valuations come from AI?

I do not use AI or automated valuation systems in my valuation work. AI answers are not equivalent to independent expert evidence prepared for legal proceedings. Every report prepared by Specialist Car Valuations report is individually researched, assessed and signed by me. I am personally accountable for my professional opinions and can explain and defend my conclusions when challenged.
